1 Claim.

This invention relates to a sealing device and as its principal objectaims to provide an improved sealing device for use on doors or the like,and which is movable relative to the door and adapted to be projected tosealing position or retracted therefrom by such relative movement.

Another object of my invention is to provide a sealing device of simpleand inexpensive construction which can be readily applied to a door orthe like and which has a sealing element adapted to be projected orextended in response to closing movement of the door.

Still another object of my invention is to provide an improved sealingdevice embodying an elongated sealing member and adapted to be appliedto a door with such sealing member substantially coextensive with anedge of the door and also having means engageable with the door frame toshift the member to sealing position during closing movement of thedoor.

Yet another object of my invention is to provide an improved sealingdevice comprising Van elongated casing adapted to be applied to a dooradjacent an edge thereof and having therein an elongated sealing memberand means whereby such member is projected and retracted in response tomovements of the door toward and from its closed position.

It is also an object of my invention to provide an improved sealingdevice comprising an elon gated casing having therein a correspondinglyelongated sealing member and operating levers pivoted to act on, thesealing member to project the same, and in which the levers are adaptedto be swung by movement of an actuating member having a part extendingfrom lthe casing.

Still another object of my invention is to provide a door sealingdevice, of the type referred to, which is contained in a recess providedinteriorly of the door adjacent an edge thereof.

My invention may be Afurther briefly summarized as consisting in certainnovel combinations and arrangements of parts hereinafter described andmore particularly set out in the appended claim.

In the accompanying drawing to which more detailed reference will now bemade, I have shown what I regard to be preferred forms of my sealingdevice, but before proceeding with the detailed description it should beunderstood that the invention may be applied to various uses and may beembodied in various other devices `and constructions.

In Fig. 1 of the drawing I show a door it) which is hinged at one sideedge thereof to a door frame ll as by means of hinges l2. My improvedsealing device I3 is shown applied to the inner face of the dooradjacent its lower edge. As will be presently explained more in detail,this sealing device may include a casing ill which has a slotlikeopening along its lower edge and is adapted to be mounted on the doorwith its slot-like opening substantially coextensive with the lower edgeof the door. The device also includes a sealing member l5 movable in thecasing and adapted to be partially projected or extended therefrom intosealing engagement with the floor i6 when the door is moved to itsclosed position.

As illustrated in Figs. 2, 3 and 4 of the drawing, the casing M may bean elongated, generally dat, sheet metal member of channel-like crosssection having spaced side walls lil and i9 between which the sealingmember is movable. The casing is preferably closed at its ends by walls20 and 2| of substantially the same depth as the side walls I8 and I9.

The sealing member l5 may comprise an elongated sheet metal stiifeningmember or holder 23 of substantially channel-like cross-sectional shapeand a strip 24 of flexible or resilient sealing material, for examplesponge rubber, which is `gripped or otherwise held in the stiieningmember. The sealing member is also generally flat and of a thickness tobe freely slidable in the casing so that it can be projected from, or

retracted into, the slot-like opening along the lower edge thereof. Theframe or holder 23 of the sealing member may have curved, linger-likeintegral extensions 24a. adjacent its` ends which slidably engage theend walls of the casing and provide a means for guiding the movements ofthe sealing `member therein.

For actuating the sealing member l to project or extend the same fromthe lower edge of the casing, I provide a plurality of levers 25 whichare mounted for swinging or rocking movement Within the casing by meansof trans.- verse pivots. These pivots may be in the form of a hollow oreyelet rivet 26 extending through the side walls I8 and I9 of the casingwith a bushing 21 disposed around the stem of the rivet to prevent theside walls from being deflected inwardly and binding against the movableparts contained in the casing. These hollow rivets also provideconvenient openings for screws 26a with which the device may be heldagainst the face of a door, as illustrated in Fig. 1. The levers 25 mayhave their lower ends connected with the sealing member |5 as by meansof pin and slot elements 29 and 30 so that the sealing member issuspended from the levers.

For rocking the levers 25 on their pivots to cause the sealing member l5to be extended from the casing or retracted thereinto, I provide anelongated actuating member or bar 3| which is shiftable in the casingand with which the upper arms of the levers may be connected. Theoperating connection between this member and the levers may be formed byproviding the member with longitudinal slots 32 into which the upperarms of the levers extend and a transverse pin 33 which extends througheach lever arm and pivotally connects the same with the slotted portionof the actuating member.

It is a feature of my invention that this actuating member 3| has a part35 extending from the casing |4, for example through an opening of theend wall 2| for engagement with the door frame or a striker plate 36mounted thereon, or through a side wall as a knob 35 for manualoperation of the sealing member as illustrated in Fig. 8. The projectingpart of the actuating member 3| may be an integral part of this bar orif desired it may be a member screwed into the bar and adjustable tovary the extent of travel of the sealing member I5. When the projectingpart is a manually operable knob, as in Fig. 8, it may project through aslot 34 which has an angularly extending portion for retaining thesealing member in its extended position.

For retracting the sealing member |5 into the casing I4 I employ springmeans, preferably in the form of a coiled compression spring 37, whichacts against the member 3| to shift the same in a direction to causelifting of the sealing member by the levers 25. This spring may bearranged as shown in Figs. 2 and 3 between the end wall 20 of the casingand a shoulder 38 provided on the bar. The spring may be retained inplace by a stem-like extension 33 of the bar extending thereinto.

Instead of having the sealing member sus.- pended from the rockinglevers it may be desirable to suspend the sealing member by means oftension springs 40. These springs may have their lower ends connectedwith the frame or holder part 23a of the sealing member and their upperends connected with the casing itself or with the actuating bar 4| bymeans of a saddlelike part 4|a through which the bar is slidable.Instead of the levers shown in Fig. 2 I may employ levers of the formrepresented by the lever 42 of Fig. 5 of which the lower arm may beprovided with a rounded or cam-like portion 43 for rocking engagementwith the frame of the sealing member. It may also be desirable tosimplify the connection between the swinging levers and the actuatingmember and this may be accomplished by providing the actuating memberwith an offset section 44, as illustrated in Fig. 6, with which theupper arm of the lever is connected by means of the pivot pin 45.

With the arrangement which I have illustrated it will be noted that therocking levers have arms of unequal length so that a relatively shorttravel of the actuating member or bar will be amplified and will resultin a greater extent of movement of the sealing member.

In some instances it may be desirable to have the sealing deviceconcealed by the structure of the door instead of having it exposed asit is when secured against the face of the door by means of screws orthe like, as shown in Fig. l. Such concealment of the sealing device maybe readily provided for by locating the device I3 within a recess 4lformed interiorly of the door 48 along the lower edge thereof, as shownin Fig. 7. This arrangement for the sealing device is also desirable forthe reason that it locates the projecting actuating part 49, whichengages the door frame or striker substantially in the central plane ofthe door.

From the foregoing description and the accompanying drawing it will nowbe readily seen that I have provided a sealing device of simple andinexpensive construction which can be readily applied to a door or thelike and which has a sealing member adapted to be projected andretracted either manually, or automatically in response to movements ofthe door toward and from its closed position. Since the sealing meinberof my device will, when operated automatically, be retracted into thecasing as soon as the door begins to swing open, it will be readily seenthat the sealing member will not scrape over the surface of the iioor orcarpet to cause marring or wear and will not cause rumpling ordisplacement of a rug or mat located adjacent the door opening.

While I have illustrated and 4described the improved sealing device ofmy invention, it will be understood, of course, that I do not wish to belimited to the precise details of construction and arrangements' ofparts herein disclosed, but regard my invention as including suchchanges and modications as do not constitute a departure from the spiritof the invention and scope of the appended claim.

Having thus described my invention, I claim:

In a sealing device of the character described the combination of anelongated hollow casing having end and side walls and a slot-likeopening, and an elongated sealing member in said casing adapted to bepartially projected through said opening comprising a channel-shapedmetal bar and a packing strip carried thereby, said metal bar havingcurved integral finger-like extensions forming bearing portions at theends thereof for guiding engagement with the end walls of the casing.
